Important: For clients running Windows 7 SP1, it is critical to install all Windows security patches before applying the patch.

If the SafeGuard Client 8.00.0.251 is already installed

  1. Copy the installer patch file to the corresponding computer(s).
  2. Apply the SafeGuard Client Rollup patch.
    Example: msiexec /update C:\Install\SGN8006Patch1908_x64.msp
  3. Reboot the machine for the changes to take effect. After installing, the machine gets automated reboot if installation done via command line. If you want to control the reboot, use the /norestart switch.

If the SafeGuard Client 8.00.5.x is already installed

  1. Copy the installer patch file and the SGN8006Patch1908.cmd to the corresponding computer(s).
  2. Run the SGN8006Patch1908.cmd in an administrative CMD. This will ensure that the pre-requisites are met and the Patch gets installed.
  3. Reboot the machine for the changes to take effect.

Installation of SafeGuard Client with the patch

  1. Copy the SafeGuard Client and the installer patch files to the corresponding computer(s).
  2. Install the SafeGuard Client with the Rollup patch.
    For example: msiexec /i C:\Install\SGNClient_x64.msi PATCH=C:\Install\SGN8006Patch1908_x64.msp
  3. Reboot the machine for the changes to take effect. After installing, the machine gets automatically rebooted if the installation is done via command line. If you want to control the reboot, use the /norestart switch.

How to verify if the patch is applied

The security and compatibility patch comes in the form of a Windows Installer Minor Upgrade Patch and updates the version number of the Sophos SafeGuard Client that is displayed in Apps & features / Programs and Features to 8.00.6.2

Additionally the version in the SafeGuard about box has been updated and the clients report the new version using the machine inventory, which can be displayed in the SafeGuard Management Center.

Limitations: This Hotfix Rollup is not compatible with SafeGuard LAN Crypt.
